Ok, let's try this. I have a number of springs in a circle applying force on a disc. The disc is in balance as long as I have the springs equally spaced. I want to try to maintain an equal balance of force all the way around. There would never be a situation where there would only be one spring...

Think of the marble as a single point fulcrum. The disc is sitting on top of it along the X plane. All the forces are directed down (negative Y direction). Applying a force on the edge of the disc will result in the other end of the disc to act in the opposite direction, like a teeter-totter. If...

This seems like it would be pretty simple and I apologize if this is in the wrong area, here goes. Picture a flat disc. It is supported by a pin or marble in the center. There are no forces acting on it. Now at 0 deg, I apply a force F (all forces are a distance equal from the center)...

Hello, I would like to know how to determine the max RPM of a disc. I would think it would be the centrifugal force against the Yeild Strength. Any help would be appreciated. Thanks, Ron

This is not a homework problem, Is there someone who understands this enough to at least tell me if what I am doing is wrong. Inertia is a bodys resistance to motion, I have a steel disc, with its weight and diameter I can calculate its inertia, it is spinning at 600 Revolutions per minute. I...

I am testing a brake Ok, I know I have 1366.5 LB-Ft2 of material spinning at 600 RPM, I stop that in 1.45 seconds. What is the torque generated to do that. I would think that gravity would not be a factor but when I ommit the gravatational constant the results I get are not really...

I would like someone to confirm, comment on my understanding of torque calculations of a rotating body. Formula: T=I\alpha I=LB-FT2 (1366.5) Known \alpha=Rad/s2(43.33) Angular acceleration from 600-0 RPM in 1.45 sec Now I believe I need to divide by 32.2 ft/s2 (accelleration of gravity)...

Thank You nvn It looks like nvn has awnsered my question but I will clarify to both clean up the post. The top "equation" is an attempt at a free body diagram with the underline representing the supported object. N=number of springs, by fall I mean delta (the amount an object moves).

FW+(Spring Force 2)K2N2(D2-Delta) (spring force 1)K1N1(D1+Delta) I have a spring set(springs in parallel) on top of an object and a spring set supporting the object. The weight of the object is represented by FW. The bottom springs are F1 and the top springs F2. There is preload on...
